That error usually occurs when the available display on node 0 is larger
than one or more of the other displays in your cluster.  I'm surprised
this only happens in reverse connect, it generally has nothing to do
with the direction of the connection.  At any rate, work with your
system administrators to make sure X Windows is set up to have the same
size display on all nodes in your cluster.

I dunno.  Maybe your system administrators can help you hash out issues
with X Windows permissions.

That is not uncommon with some implementations of MPI.  When the server
is sitting at idle, node 0 is listening for a socket while all others
are sitting in an MPI_Recv call.  Some implementations of MPI must
implement MPI_Recv in a loop that constantly polls for incoming data (I
guess).  At any rate there is nothing we can really do about it.
